Description

Technical Field

[0001] The utility model relates to the technical field of material evaporation, in particular to a built-in scraper evaporator. Background Art

[0002] In the chemical industry, evaporators are very commonly used heat exchange equipment, mainly used for heating or cooling liquid materials.

[0003] At present, most of the commonly used evaporators are external and tube-in-tube type. The material to be heated is placed in the heating tube, and the tube is heated by steam. The thermal efficiency is low, the heat loss is large, the energy consumption is high, and it is not easy to clean. In particular, when heating some liquid materials with high viscosity and easy to scale and clog, such as magnesium fluorosilicate and zinc fluorosilicate, it is very easy to cause clogging, inconvenient to use, and short life. For this reason, we provide a built-in evaporator (specifically refer to patent number: 201320658504.3), including a tank body, the top of the tank body is provided with a feed inlet and an exhaust port, the bottom of the tank body is provided with a discharge port, and a heat exchanger is provided in the tank body. The heating tubes between the upper and lower baffles of the heat exchanger are arranged in a spiral S shape, and the steam inlet pipe and the condensed water outlet pipe are respectively connected to the heat exchanger. The utility model has the advantages of high thermal efficiency, low heat loss, not easy to clog, easy to clean, corrosion resistance, high temperature resistance, long service life, etc., and is particularly suitable for heating materials with high viscosity and easy to scale and clog such as magnesium fluorosilicate and zinc fluorosilicate.

[0004] However, some existing built-in evaporators can only perform a single heating operation on the material when in use, resulting in low heating efficiency, inability to quickly heat the boring material, and poor practicality. At the same time, during the heating operation, some materials will agglomerate and adsorb, causing clogging of the device, making it inconvenient to use and troublesome to clean.
